CVE-2019-10589Network attack vector

Memory corruption via unchecked GP response length

Published Apr 16, 2020 · Updated Aug 4, 2024

Buffer overflow in GP command response handling in Qualcomm Snapdragon platforms allows remote attackers to corrupt memory via oversized responses. The handler writes a GP command response into its response buffer without first checking that the response length fits the destination. Network access and no authentication are required; Qualcomm has not disclosed whether the resulting memory corruption causes a crash, code execution, or another effect.
